In 1960s, I observed some creatures creeping on the wall of our house. When I tried to catch them, they ran and escaped behind wall-hanging calendars. Even if I caught one of them gently, it slipped away to safety leaving behind a silvery white powder on my fingers - just like a moth leaves its scales! It is the Silverfish (Lepisma saccharina, Fishmoth, 'Velli poochi' in Tamil).
